Title: Motor controller
Inventor: HARA MASAHIKO
IPC: H02P6/12
Filed: 1998-12-03
Abstract: PROBLEM TO BE SOLVED: To eliminate the need for regulating the control gain by taking in the motor current a plurality of times, in synchronism with the speed control sampling time and then setting the optimal control gain constant automatically and selectively, based on a data base which is preset with averaged current values. SOLUTION: In case of an air volume controller, an AC voltage is applied and converted into a DC voltage by a rectifying bridge (b) via a noise filter (a). Furthermore, although the DC voltage is smoothed through a switching transformer (c) and divided into high and low voltages, the high voltage line enters a transistor module (e) and drives a motor (f) which has an output shaft fixed with a fan (g). The low-voltage line serves as the feeder for a microcomputer (h) or a TTL and so on, and the microcomputer (h) controls the drive command of the transistor module (e) by fetching a speed control signal, signal from a host, Hall IC signal or FG signal from the motor. As a result since a work for switching the gain value can be eliminated, product cost can be lowered.

Title: Gas laser oscillation apparatus
Inventor: TAKAGI SHIGEYUKI
IPC: H01S3/097
Filed: 1989-12-28
Abstract: PURPOSE:To enhance safety by a method wherein a terminal voltage of a switching element is detected by using a voltage detection circuit and, when the voltage is in a prescribed voltage region, a switching permission signal is sent out to a pulse high-voltage power supply from a switching permission circuit. CONSTITUTION:A grid voltage of a thyratron 2 is detected. when the voltage is a comparison voltage vk or lower, a switching permission signal is sent out to individual thyristors 8, 9 of a pulser high-voltage power supply 1. A pulse energy is output from the pulse high-voltage power supply 1, a main capacitor 3 is charged, the thyratron 2 is ignited, the pulse energy is supplied to a gas laser tube 4 and a laser is oscillated. Consequently, the pulse energy is not output from the pulse high-voltage power supply 1 until the thyratron 2 is restored and while the thyratron 2 is abnormal. Thereby, a large electric current does not flow to the secondary side of a pulse transformer, and safety is enhanced.

IPC: B60T8/66
Filed: 1992-12-25
Abstract: PURPOSE:To accurately calculate estimated car body speed by using a value obtained by adding variation defined by threshold deceleration to estimated car body in a previous cycle as estimated car body speed in a current cycle if wheel deceleration exceeds threshold deceleration. CONSTITUTION:When a step #8 judges that current wheel speed SPEED is smaller than a value obtained by adding decreasing maximum speed (-DELTAWREF) to previous vehicle speed WREF, or the current wheel speed SPEED exceeds a preset range (-DELTAWREF) from the previous inferred vehicle speed WREF and smaller, it moves to a step #9. In case of this wheel, judgement is made that a sign of locking or skid appears. The current inferred vehicle speed WREF is set to be a value obtained by adding the decreasing maximum speed (-DELTAWREF) to the previous inferred vehicle speed WREF. The threshold value of deceleration (-DELTAWREF) is set on the basis of the liquid pressure of a wheel cylinder and so it can be set larger (smaller) on a high (low) mu road surface.
